You're right. IMHO we should first get a clear picture, which problems
actually arise. (unfortunately, I can't easily flash firmware on my
DUTs for several reasons, eg. I dont actually own them :o).

If it's just about duplicate LEDs, we could either just ignore that
or add yet another  board specific quirks in the acpi probing for
ignoring the duplicate devices - depending on the existing kconfig
symbol.
